Worcester 18i system boiler air problem.

fullyuntrainedplumber · 9 Sep 2010

My WB 18i system boiler seems to have air in the water-heating piping which has an auto bleed valve fitted. The heating seems OK as I have bled the radiators, but this does not seem to remove the air as there is a washy sound near the pump and in the pipe work . Is it possible to bleed the boiler to remove this air or should this air be removed when I bleed the radiators, as I have bled them many times and there is no air in the rads.
Apologies if I have not explained it well.
Cheers
Bill
